Answer 2

Imagination plays a key role because of its ability to give us clues.

A basic unit of grammar made up of a noun phrase and a verb phrase is called a clause.  

In most cases, to get the entire meaning of the clause, the verb phrase can be followed by adjuncts, objects or complements. Independent clauses, subordinate clauses, finite clauses, non-finite clauses, and relative clauses are the different kinds of clauses.  

Clauses of the same grammatical fiber can be put together to make sentences using coordinating conjunctions.
